one more weird thing I noticed -when I changed the egw base from my other 110 to this one the front screw was to long to get tight -
I always tighten front screw 1st as to make sure it dont bottom out
I had a shorter screw from a weaver base
so I look in the hole & see barrel threads - but this same screw worked on my other 110 -
the barrel nut indicates its a small shank - but why the difference in depth ?
